Referring to fig. 2 in combination, fig. 2 is a functional block diagram of a base according to an embodiment of the present disclosure. The base 10 includes an input bus bar, an output bus bar, and at least one connection portion 11. The at least one connection portion 11 is electrically connected between the input bus bar and the output bus bar. Wherein the input bus is used for receiving the power supply of an external power supply. Each of the connection portions 11 is used to mount one power supply module 20. The output bus is adapted to be connected to at least one load 400 to supply power to the at least one load 400. Here, the load 400 refers to a component of the communication device that needs to be supplied with power.
When at least one power module 20 is mounted on the base 10 through the at least one connection part 11, the at least one power module 20 is electrically connected to the output bus and supplies power to the at least one load 400 through the output bus. In addition, when the power supply module 20 is installed on the connection portion 11, the base 10 is hermetically connected to the power supply module 20, so as to ensure that the outdoor communication power supply device 100 meets the requirements of the outdoor power supply environment.
It should be noted that the input bus and the output bus can also perform signal transmission with connected devices. For example, the input bus may be in signal communication with an external power source connected thereto, and the output bus may be in signal communication with a load.

As shown in fig. 3, the at least one power supply module 20 includes at least one of a rectifier module, a high voltage direct current output module (HVDC module), a battery module, a photovoltaic module, a DC/DC module, and a power distribution module.
Specifically, the rectifier module is used for converting alternating current into direct current. The HVDC module is used for outputting high-voltage (such as 380V) direct current. The battery module is used for storing energy and providing corresponding direct current electric energy. The photovoltaic module is used for converting light energy into electric energy. The DC/DC module is used for converting the first direct-current voltage into a second direct-current voltage. The second dc voltage may be greater than the first dc voltage or less than the first dc voltage, which is determined according to actual requirements. The power distribution module is used for dividing the existing voltage into a plurality of paths and then outputting the paths. The voltages of the paths may be the same or different according to specific load requirements.
In one embodiment, the number of the connecting portions 11 should be greater than or equal to the number of the power supply modules 20 in order to simultaneously plug in as many power supply modules 20 as possible to ensure power supply output.
In addition, in one embodiment, any two connection portions 11 are electrically connected to each other. Thus, when the input bus is not connected to the power supply, one of the power supply modules 20 may also supply power to the load 400 through the other power supply module 20, so as to meet the power supply requirements of different loads 400, for example, the battery module may also supply power to the other loads 400 after converting the voltage through the DC/DC module while supplying power to one load 400, and the power supply module and the connection portion may be arbitrarily mixed and inserted without limitation.
Referring to fig. 4, fig. 4 is a functional block diagram of an outdoor communication power supply device according to another embodiment of the present application. In this embodiment, the base 10 further includes a monitoring module 13. The monitoring module 13 is electrically connected to the at least one connecting portion 11, and is configured to monitor whether the power supply module 20 is installed on each connecting portion 11, that is, whether the power supply module 20 is electrically connected to the connecting portion 11. When it is monitored that the power supply module 20 is installed on a certain connecting portion 11, the voltage and the current of the power supply module 20 can be detected, so as to determine whether the power supply module 20 is in fault, thereby improving the reliability of power supply.
Specifically, a monitoring pin may be provided at each connection portion 11 for monitoring whether the power supply module 20 is mounted in the connection portion 11. For example, when the power module 20 is installed on the connection part 11, the monitoring pin outputs a low level, and when the power module 20 is inserted into the connection part 11, the monitoring pin outputs a high level, so that whether the power module 20 is installed on the connection part 11 can be monitored through a change in the level of the monitoring pin.
In addition, the monitoring module 13 can also monitor and manage the whole power system to obtain the voltage and current of the communication power system, and further obtain the system status information to ensure the normal operation of the outdoor communication power supply device 100. In one embodiment, when the power supply module 20 includes a battery module, the monitoring module 13 may be further configured to monitor the temperature and the current of the battery to obtain the battery status information. In addition, the monitoring module 13 may be further configured to monitor the current of the load 400 to obtain load status information.
